Seborrhoeic keratoses begin as well-delimited, brown-to-tan macules. Eventually, the surface becomes polypoidal and wart-like. A plaque may form. There are characteristic prominent follicles filled with keratotic material. Classically, they are described as having a stuck-on or waxy appearance.

Lesions may orientate themselves in the direction of skin folds. There may be 'crops' of lesions in an individual. The colour may vary from light brown through pink to black.

Patients may present because lesions:

  • recur - shedding top layers then reforming
  • bleed
  • itch
  • have surrounding inflammation
  • are heavily pigmented with malignant concerns
